Type FF FloorFast®

An innovative floor fixing for securing steel chequer plate flooring to the supporting steelwork without the need for on-site drilling or welding.

View technical specification

Overview

The Type FF FloorFast fixing eliminates the need for costly scaffolding or elevated floors as access to the underside of the flooring is not required. Installation is carried out quickly and safely from above, often by one person, significantly reducing costs. The cast body along with the unique stepped clamping face, which locks under the steelwork, provides outstanding clamping force and a secure connection.

Features & Benefits

  • Superior clamping force from the cast body.
  • Lloyd’s Register Type Approval for resistance to shock and vibration.
  • Zero protrusion above the surface of the floor plate.
  • Designed for pedestrian walkways only.
  • Not suitable for tapered flanges.
